Square Enix just released a demo for Minna de Wai Wai! Spelunker on the Nintendo Switch eShop, where you can try out the early stages of the game’s first world with co-op action.
The demo allows you to play 1-player, TV Mode, and Tabletop Mode with Joy-Cons. Four player offline co-op will also be available for the demo. The full release version will have online multiplayer, but this feature isn’t in the demo.
Minna de Wai Wai! Spelunker releases in Japan on April 20, 2017 for Nintendo Switch.
